Once the surfaces to be coated are clean, dry and free from all contamination, grind down any sharp edges and shot blast to Sa2½ (as defined in ISO 8501-1) with an average surface profile of at least 50 microns. As an alternative to shot blasting, mechanically prepare the surfaces to St3-C or St3-D (as defined in ISO 8501-1). Painting should then be carried out within four hours.
Ensure the surfaces to be coated are clean, dry and free from oily residues and other contaminates. New, bright, galvanised steel may be oiled or chemically treated and this surface layer must be cleaned, degreased and tested by application of Mordant Solution to a small area. If the area of application turns entirely black, paint can be applied directly to the metal. If the colour change is uneven or fails to occur, degrease and repeat the test.
Thoroughly wash and allow to dry. Remove any remaining contamination with a suitable degreaser and wipe with clean cloth or disposable paper towel. Localised repairs or damage should be lightly sanded to remove loose or flaky material until a sound edge is achieved. There is a tendency for the plasticisers in the Plastisol Coating to migrate in to the paint film and become tacky. This effect can be minimised by application of 200:026: Primer and allowing 30 mins drying time before proceeding.
Once the surfaces to be coated are clean, dry and free from all contamination, remove loose flaky paintwork back to a firm edge then lightly flat to give a smooth surface with an adequate key. Apply the material to a small test area to ensure there are no adverse reactions with the existing coating before painting can be carried out.
Do not apply or dry when the air or substrate temperature is below 5°C or in excess of 30°C otherwise film appearance and coating properties may be adversely affected. Surface temperature must also be a minimum of 3 °C above dew point. Outdoors preparation, painting and drying should only be undertaken during good weather conditions and never when rain is imminent or on days when a drop in temperature could result in condensation forming on the paint during the initial drying period or overnight. Mix thoroughly before use. Best results will be achieved using a power mixer.
Airless or airmix spray systems
Flush all lines with a compatible solvent before application to avoid ‘throw out’ and blocking of the filters. Using a brush to provide a ‘strike coat’ on difficult to reach areas such as internal welds, rough spots, bolts or corners before application of the spray coat is a good method of ensuring adequate build is achieved. One even coat applied in parallel passes, overlapping 50% on each pass to avoid bare areas, pinholes or holidays, at the stated W.F.T. is satisfactory for most purposes. However, should additional coats be required for higher film builds or blast cleaned profiles these should be applied after 15 minutes or when the film is touch dry.
Conventional or H.V.L.P. spray systems
Add thinner as required to achieve the correct atomisation but care should be taken not to over thin as this will greatly affect the performance and build of the material resulting in additional coats to achieve the required build. A full even coat should be applied in parallel passes, overlapping 50% on each pass.
Brush or Roller
Slight thinning may be required. Care should be taken not to over brush or lay-off the material. Best practice is to apply a generous even coat to a manageable area to help maintain a suitable wet edge. This material has limited capabilities when coating large areas or panels due to the speed of drying and is therefore recommended for small areas only. Subsequent coats of this material are not recommended by brush or roller application. However, should they be necessary allow the first coat to dry overnight to prevent possible reaction.
